  • the invention has for its object a tool of the type mentioned above Form so that it is easy to hit a hole of a defined depth and allows the expansion anchor to be set to a depth that is matched to the depth of the hole.
  • the Tool according to the invention has a mandrel for driving into the porous masonry on. Compared to drilling a hole, punching in a mandrel has the same effect Advantage that the masonry is compacted in the area of the hole and thus solidified and thereby gives better support to the expansion anchor to be set. Another advantage is that no drilling dust has to be removed from the hole.
  • the tool points at a predetermined distance from a front end of the mandrel a depth mark indicating that the intended hole depth has been reached indicates if it is, for example, flush with a surface of the masonry.
  • the tool assigns a receptacle for the setting expansion anchor.
  • the recording is for example for plugging on the Expansion anchor trained.
  • it fixes the expansion anchor in the axial direction on the tool at a defined distance from a second depth marking that the reaching indicates an intended setting depth of the expansion anchor in the borehole if it for example, is flush with the surface of the masonry.
  • the invention has the Advantage that making the hole and setting the expansion anchor with one Tool is possible.
  • the invention has the advantage that the hole depth and Setting depth of the expansion anchor are coordinated.
  • the first depth marking is a depth stop for example in the form of a covenant on the tool.
  • the thorn of This allows tools to be hammered into the masonry until the depth stop comes on lies against the surface of the masonry.
  • the front end of the mandrel is preferably tapered like a nail educated. This reduces the driving resistance. Furthermore, it will Masonry material pushed radially outwards when driving in the mandrel, the Masonry thus compacted in the peripheral area of the hole and thus solidified. Of the tip also guides the mandrel when it is driven into the masonry.
  • the tool according to the invention shown in FIG. 1, designated overall by 10 has the shape of a mandrel 12 and is for clamping in a not shown Keyless chuck formed with grooves 14 at its rear end.
  • the mandrel 12 has a collar 16, which is integral with it, as a depth stop on.
  • a front end 18 of the mandrel 12 is pointed like a nail.
  • Tool 10 can be a cylindrical blind hole of defined depth in one porous masonry, for example in gas concrete, by driving in the mandrel 12, for example with a hammer until the depth stop 16 on a surface of the Masonry comes to the plant, manufacture.
  • the invention is also suitable Tool 10 for driving into a porous masonry with a known per se Impact drill or a hammer drill using their impact mechanisms, the rotary movement of the drill or hammer drill is not when driving in to disturb.
  • the receptacle 20 for one shown in Figures 2 and 3 Expansion anchor 28 formed.
  • the receptacle 20 has a ring step 22 which the mandrel 12 tapers towards the front and on which it turns into a short cylindrical Extension 24 merges, which ends with the tip 18.
  • the ring stage 22 forms one Stop for the expansion anchor 28, this when it is placed in a with the mandrel 12 Hole fixed in the axial direction on the mandrel 12.
  • the ring stage 22 has a defined one axial distance to a circumferential groove 26 which is at a defined distance is attached behind the ring step 22 on the mandrel 12.
  • the ring step 22 of the mandrel 12 closely forms a complementary ring step the reason of a hole made with the tool 10 according to the invention.
  • the Ring step 22 has a defined distance in the axial direction from the depth stop 16, so that the complementary ring step of the hole produced at precisely defined depth located under a surface of a masonry.
  • the extension 24 of the receptacle 20 is provided for attaching the expansion anchor 28 and aligns it with the mandrel 12.
  • the tool 10 according to the invention shown in FIG. 1 is for setting a Expansion anchor 28 is provided, as shown in Figures 2 and 3.
  • This Expansible anchor 28 comprises a hollow cylindrical anchor body 30, from which forward Protruding tongues 32 protrude in the longitudinal direction.
  • the anchor body 30 is made of one rectangular, formed into a hollow cylinder sheet metal part, on the front end, the expansion tongues 32 are formed by slits in the longitudinal direction.
  • the anchor body 30 In its rear area, the anchor body 30 has an internal thread 34 for Attach an object to the expansion anchor 28 after setting.
  • the Interior of the anchor body 30 forms recess 35 for receiving and guiding a shaft 38 of an expansion body 40.
  • the shaft 38 of the expansion body 40 is conical Spreading area recorded, which projects forward over the expansion tongues 32.
  • the expansion body 40 can also be rotationally symmetrical, for example, in a wedge shape with a tongue-shaped shaft of rectangular cross section (not shown).
  • the anchor body 30 has a cross-sectional constriction 42 in an area behind the End of the shaft 38 of the expansion body 40 when it is in front of the expansion tongues 32 is located.
  • the cross-sectional constriction 42 can be circumferential, for example by rolling or also produced by pressing in at one or more points on the circumference his.
  • the expansion anchor 28 placed on the receptacle 20 of the tool 10 and into that with the tool 10 manufactured blind hole inserted and driven.
  • the expansion body 40 on the Ring step 46 which the ring step 22 of the tool 10 near the bottom of the hole in the hole has formed, comes to rest, the expansion body 40 is retained by this ring step 46.
  • the expansion tongues 32 slide on the conical one Spreading body 40 and are spread apart obliquely by this.
  • the Spreading tongues 32 penetrate into the masonry 44 through a peripheral wall of the hole a, as shown in Figure 3.
  • the expansion anchor 28 has reached its intended expansion position when the second depth marking 26 of the tool 10 flush with a surface 48 of the Masonry 44 is. This ensures that the expansion anchor 28 as intended is anchored in the masonry 44. Neither is it driven in too deeply, which leads to a unwanted expansion of the anchor body 30 and cracking between the Spread tongues 32 can lead, the expansion anchor 28 is not driven enough and consequently his spread tongues 32 spread too little.
  • the shaft 38 of the expansion body 40 enters the cross-sectional constriction 42 of the anchor body 30, which with a clamp connection forms the shaft 38 and fixes the expansion body 40 in the anchor body 30, so that the Do not detach the expansion body 40 from the anchor body 30 and move it out of the expansion tongues 32 can.
  • This ensures that the expansion anchor 28 in a form-fitting manner Masonry 44 is anchored and the expansion tongues 32 are not along the expansion body 40 can be pulled out of the masonry 44.
  • the one that forms the clamp connection Cross-sectional constriction 42 then reliably connects the expansion body 40 with the anchor body 30 when the latter by spreading its expansion tongues 32 is expanded. Such widening is possible if the anchor body 28 as in FIG Embodiment from a sheet metal formed into a hollow cylinder with a continuous longitudinal slot exists.
  • the tool 10 can be pulled out and by screwing a screw, not shown, into the internal thread 34 Attach the object to the masonry 44.
  • the axial distances from ring step 22, second depth marking 26 and depth stop 16 on the mandrel 12 of the tool 10 matched to one another in such a way that the expansion tongues 32 are spread out as intended, if the expansion anchor 28 so far with the tool 10 in a hole in the masonry 40th has been driven in that its second depth mark 26 with the surface 48th of the masonry 44 is flush after the hole by driving in the tool 10 has been made in the masonry 44 to the depth stop 16.
  • the expansion anchor 28 a defined piece is driven in under the surface 48 of the masonry 44, so that by screwing in a screw when attaching an object can be pulled towards the surface 48 of the masonry 44 until it gives a firm hold.
